How to resolve the issue of being unable to delete the current user in PL/SQL?

In PL/SQL, it is not possible to directly delete the current user’s connection. To address this issue, you can try the following methods:

1. Create a new administrator user: Start by creating a new user with administrator privileges. Log in with this user and make sure they have enough permissions to delete the currently connected user.
2. Disconnect the current connection: To disconnect the current user using a new admin user, you can use the following statement:
3. Terminate a session using the command “ALTER SYSTEM KILL SESSION” followed by the session ID and serial number.
4. You can use the following query to retrieve these values: represents the session ID, and represents the session serial number.
5. Retrieve the session ID and serial number from the v$session view where the username is equal to ‘‘.
6. Note: Please replace with the username of the user to be deleted.
7. Delete user: Using the new administrator account, follow these steps to remove the user:
8. Remove user completely and all associated objects.
9. Note: You need to replace “” with the username of the user you want to delete.
10. Reconnect: Reconnect to the database using the new admin user to verify if the user has been successfully deleted.

Please proceed with caution, as this operation will delete all objects and data associated with the specified user, and cannot be undone. Make sure to backup the database before proceeding with this operation.
